RDL’s DD-BN22 Wall-Mounted Bi-Directional Mic/Line Dante Interface
In this week’s featured Application Spotlight, we shine the light on RDL’s DD-BN22 Wall-Mounted Bi-Directional Mic/Line Dante Interface and delve into its crucial role in system design for large venues like convention centers, resorts and hotels, entertainment venues, amphitheaters, and corporate conference and meeting rooms.
At the heart of this Dante wall plate product lies its professional-grade construction, boasting discrete mic preamplifiers that deliver studio-quality fidelity and exceptional noise performance. The unit comprises two female and two male metal XLR jacks elegantly housed within a durable stainless steel chassis. Notably, the DD-BN22 offers physical configuration without the need for any software adjustments.
Each XLR input is equipped with three front-panel switches, which can be set prior to installing the cover plate. These switches serve various functions, including enabling or disabling P48 phantom power, selecting the mic or line gain range, and setting the gain itself. On the rear panel, additional switches allow for individual XLR output configuration, offering flexibility between mic and line level settings.
The DD-BN22 finds its ideal application in scenarios where the settings are typically configured once to meet the system’s requirements. A prime example is a large convention center or hotel ballroom that employs airwalls to create smaller rooms within the larger space. In such cases, the DD-BN22’s inputs and outputs are commonly set to line level.
For instance, in a subdivided room section hosting a breakout meeting, a presenter may only require audio inputs for a microphone and computer audio. In this scenario, a compact 4-channel audio mixer would suffice, with its XLR line level outputs seamlessly connecting to the DD-BN22’s inputs. The audio signal is then converted and transmitted to the Dante network, which may include a Digital Signal Processor (DSP) for applying effects, tone adjustments, and level control. Finally, the processed signal can be routed to the existing installed amplifier and ceiling speakers within that specific room section or sent to the DD-BN22’s output jacks, feeding one or two portable active loudspeakers.
In summary, the RDL DD-BN22 Wall-Mounted Bi-Directional Mic/Line Dante Interface proves to be an indispensable tool in system designs for large venues, facilitating seamless audio integration, configuration flexibility, and high-quality sound reproduction for various applications.
